Abstract
A passive magnetic field shielding system for shielding a fringe magnetic field is described. The passive magnetic field shielding system includes a magnet configured to generate a uniform magnetic field, an imaging system with associated electronics coupled to the magnet, and a passive shield configured to reduce the strength of the fringing magnetic field to approximately five Gauss at a distance from the passive shield.
